4 C is probably all it will take for human extinction, and we will reach 4 C soon

“frustrated with this global inaction, the World Bank released a report on Sunday saying that without significant emissions reductions, the world’s average temperature could climb by 4°C (7.2°F) by as early as 2060. “

” The idea that we could adapt to a 4C rise is absurd and dangerous. Global warming on this scale would be a catastrophe that would mean, in the immortal words that Chief Seattle probably never spoke, “the end of living and the beginning of survival” for humankind. Or perhaps the beginning of our extinction.”
